Pump 13,000 liters of mineral-free water per hour at high-pressure – without using oil-based products for lubrication.
Most pumps need oil-based lubricants to keep moving parts working smoothly. And in most cases, lubricants are not a problem: the risk of contamination from well-made pumps is low, and even if there is some small oil discharge, the consequences of a minor leak are minimal.
In advanced evaporative cooling and humidification applications, however, things are different. Even infinitesimal amounts of atomized oil droplets can be enough to tip the balance between “clean” and “not clean” – and jeopardize staff health, hard-won ISO 22000 certification as well as an entire business model.
“You could say that we have bet the ranch on Danfoss’ PAHT pumps,” explains Kasper Gissel, Condair’s managing director in Denmark. “There are plenty of other companies that provide adiabatic cooling and humidification systems for data centers, but we’re not like our competition. We work in health care facilities as well as food processing, manufacturing, data and other industries. The niche we want to dominate is characterized by zero contamination – not low contamination. Legionella and other airborne pathogens like nothing better than a little oil-based fertilizer to proliferate, and that’s the last thing air treatment needs. We compete on our ability to provide consistently contaminant-free humidity, and Danfoss pumps are a cornerstone of our competitive strategy.”
